The first is a retail market posed of nonbank customers who purchase from banks what amounts to customized insurance against adverse exchange rate movements. These customers prefer the OTC market because of their ability to obtain terms that fit their needs. ? The second is a wholesale market among mercial banks, investment banks, and specialized trading firms. This market has options that are larger in contract size than elsewhere, and typically Europeanstyle. OTC Option Markets ? They are customized unlike the standardized exchangetraded options. The exchanges can be viewed as the discount stores (“onesizefits all” stores). The international banks are boutiques offering tailormade products to customers. ? Premiums on OTC options are higher than the parable exchangetraded options. This difference primarily reflects the customized nature of the OTC options。但有履約價格、期權(quán)費的特殊規(guī)定。 ? 外匯期權(quán)合同的買方是有權(quán)無責(zé)，賣方是有責(zé)無權(quán)。 ? 現(xiàn)貨市場 期貨市場 ? 12月 10日預(yù)計 3個月后支付 200 同日買進(jìn) 16份瑞士法郎期貨合約 ? 萬瑞士法郎 （ 200/） ? ＄ 1= ? （ SF1=＄ ） SF1=＄ 3月 10日用美元買進(jìn) 200萬瑞士法郎 同日賣出 16份瑞士法郎期貨合約 ? ＄ 1= ? （ SF1=＄ ） SF1=＄ 虧損 200（ ） =＄ 9200 盈利 200（ )=9200＄ 56 （三）外匯期權(quán)交易 （ Option Trading） ? 期權(quán)交易又稱選擇權(quán)交易，是指交易者通過付出一筆較小的費用，便能得到一種權(quán)利，在預(yù)先商定的日期或該日期前，按照預(yù)先商定的價格和數(shù)量買賣某一特定商品或金融資產(chǎn)的權(quán)利。 54 外匯期貨賣方保值 ? 例如：我國某出口公司 8月 2日發(fā)貨，收到 9月 1日到期的 100萬英鎊遠(yuǎn)期匯票，該公司擔(dān)心英鎊到期時匯率下降，帶來外匯風(fēng)險，于 8月 2日作外匯期貨交易保值。兩個市場價格互相影響、相互依賴 53 外匯期貨市場套期保值交易 ?外匯期貨市場套期保值交易原理是利用現(xiàn)貨市場價格與期貨市場價格同方向、同幅度變動的特點，在外匯現(xiàn)貨市場與期貨市場做方向相反、金額相等的對沖交易，以便對持有的外匯債券或債務(wù)進(jìn)行保值。為了防范風(fēng)險或投機(jī)。外匯期貨交易絕大部分（ 95%左右）每日結(jié)算， 5%左右通過買賣平倉終止交割義務(wù)；遠(yuǎn)期外匯交易大多數(shù)在交割日用現(xiàn)匯交割。外匯期貨交易信用風(fēng)險小、價格風(fēng)險大；遠(yuǎn)期外匯交易信用風(fēng)險大、價格風(fēng)險也大。外匯期貨交易采取每日結(jié)算制度；遠(yuǎn)期外匯交易在到期日進(jìn)行結(jié)算。外匯期貨交易必須交足保證金；遠(yuǎn)期外匯交易一般不收保證金。外匯期貨交易參與者可以是金融機(jī)構(gòu)、企業(yè)、公司和個人；遠(yuǎn)期外匯交易一般是大公司。外匯期貨交易合約是標(biāo)準(zhǔn)化的；遠(yuǎn)期外匯交易合約由雙方協(xié)商確定。外匯期貨交易是在有形市場；遠(yuǎn)期外匯交易是在無形市場。包括套期保值者（ Hedger）和投機(jī)者（ Speculator）兩種。收取傭金。 ? 期貨傭金商。負(fù)責(zé)期貨合同的交易與登記。制定交易規(guī)則，監(jiān)督管理交易活動及發(fā)布信息，提供交易場所與設(shè)施，以維持期貨市場的正常運轉(zhuǎn)。交割日期為到期月的第三個星期的星期三。 ? 交割月份與交割日期。 IMM中規(guī)定，加元 10萬、日元1250萬、瑞士法郎 、英鎊 。僅限于美元與另一種可自由兌換貨幣的交易。 T i m e A c t i on I n v e s t or 39。 ?
